=Upgrade in DD-WRT=

+

'''AFTER FLASHING THE TRAILED BUILD''', only use the following builds OR YOU WILL BRICK THE e3000:

+

*For builds before svn16773, ONLY USE ''e2k-e3k.bin'' builds

+

*For builds since svn16773, ONLY USE an ''E3000.bin'' trailed build

+

*If running an E3000.bin build since svn16772, you can upgrade using E3000 (trailed) or nv60k builds

+

*See [[Index:FAQ#Where_do_I_download_firmware.3F|Where do I download firmware?]] for links.

+

+

#To flash an nv60k build (that replaces e2k-e3k), you must flash a trailed E3000 build '''from svn16773 or later''' before nv60k. '''Do not flash directly from e2k-e3k to nv60k!'''

+

#*To flash another e2k-e3k build such as 15692 ('''must have e2k-e3k in the file name'''), follow these steps.

+

#Download the desired e2k-e3k or e3000.bin trailed build

+

#Hard reset the router, then login to the router at 192.168.1.1.

+

#Go to the ''Admin->Firmware Upgrade'' page and flash the downloaded file.

+

#Wait AT LEAST 5 minutes until the WLAN light turn on, then unplug power on router and wait 30 seconds.

+

#Power up and wait 5 minutes, then hard reset again

+

#Wait until it finishes booting, log into web interface, set user/password, and set up DD-WRT

+

#* Clear your browser cache if the web login does not display.

+

+

==e2k-e3k and nv60k==

+

Any build past 16773 requires a different build, rather than e2k-e3k, for subsequent flashing. In order to use one of these experimental builds, you must ALREADY HAVE dd-wrt installed on your router using the instructions above, following the steps in the [http://www.dd-wrt.com/phpBB2/viewtopic.php?t=51486 Peacock announcement] note 1.

+

+

The first Eko -nv60k build is 16773; the first official BrainSlayer -nv60k build is 16785.

+

If you have a pre-16773 build on the router then you can load either of BrainSlayers 16785 or 16994 builds with file name ending in e2k-e3k, flashing any those files will be the step stone bringing you over to -nv60k type builds.

16995 is the last dd-wrt build with upgrade files of e2k-e3k type, all upgrading thereafter is done with -nv60k type files.

+

+

==Kong Build==

+

'''[http://www.desipro.de/ddwrt-ren/K26/r22000++ Kong 22000++] is a stable, reliable, recommended large build for the E3000''' without the Heartbleed vulnerability. You can (only) upgrade to Kong from DD-WRT. (There are no trialed Kong builds.) Two versions are available:

Also it has been asked about the builds with e2k-e3k name in them, these builds when already running dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.

+

+

=Useful Tips=

+

*Cooling can be very important for E-series routers, due to the lack of airflow. It can affect performance and wireless stability. An easy mod to improve airflow under the unit is in [http://www.dd-wrt.com/phpBB2/viewtopic.php?p=475684&highlight=#475684 this post by buddee].

+

From the [[Wireless-N_Configuration]] wiki: AES security is required for 802.11n, as TKIP will force 802.11g. AES+TKIP is also allowed, but only WPA2+AES is recommended.

-

'''As of July 2010 you can only use the trailed builds with the e3000 name in it for initial flashing and nothing else, using other bin's without the e3000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then use the e2k-e3k.bin's for upgrading to newer builds.'''

= Printing =

+

[http://www.dd-wrt.com/wiki/index.php/Printer_Sharing '''Printer Sharing'''] gives a general description how to configure the router to connect a printer on the USB port. However it describes too much and things that are not needed or even not working for the E3000 router. Following procedure works with firmware DD-WRT v24-sp2 (12/24/10) mega, the latest version at the moment of writing.

+

So here a more specific description how to enable printing.

+

On the web interface of the router ([http://192.168.1.1 '''http://192.168.1.1''']):

+

* Enable "Core USB Support", "USB 1.1 Support (UHCI)", "USB 1.1 Support (OHCI)", "USB 2.0 Support", "USB Printer Support" on the Services tab (all items under "USB Support" except for "USB Storage Support"). Note that the router did not recognize my printer if I left the USB 1.1 drivers unselected. This even though the printer supports USB 2.0.

+

* It is *not* necesary to enable JFFS2 support via Administration, Management

'''Always use the E~ series builds for upgrading. Anything else will brick your unit'''

+

This indicates that a printer is detected on the USB port

+

* Now enter

+

The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.

We are especially interested in the line

tcp 0 0 0.0.0.0:9100 0.0.0.0:* LISTEN

-

ftp://ftp.dd-wrt.com/others/eko/V24-K26/

It is saying that a service via tcp is listening on port 9100

-

Brainslayer added E3000 Support from 14929 and on and builds are to be found in the broadcom_K26 folder of his build branch.

+

* And at last enter

+

root@my-ddwrt-router:~# ps | grep p9100d

+

927 root 1108 S p9100d -f /dev/lp0 0 -t 5

-

ftp://ftp.dd-wrt.com/others/eko/BrainSlayer-V24-preSP2/

+

This also indicates that a process p9100d is running looking at port /dev/lp0 which is a printer port

-

Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.

+

* You don't have to install anything via ipkg or any other script. Everything is installed by default. So if you don't have the expertise to ssh to your router, don't despair, it is only to make sure that your router recognises your printer on the USB port.

-

===Some useful tips===

+

To install the printer under Windows, use the following procedure:

-

* I have noticed with these style of linksys units, cooling can be very important to its performance, thus I have done a nice easy mod that will allow air flow for under the unit. Check this post for details. http://www.dd-wrt.com/phpBB2/viewtopic.php?p=475684&highlight=#475684 -buddee

+

Windows 7

+

* Open Control Panel, Devices and Printers

+

* Choose Add a printer

+

* Add a local printer

+

* Create a new port

+

* Type of port: Standard TCP/IP Port

+

* Hostname or IP address: 192.168.1.1

+

* Make sure that the checkbox to query the printer and select a driver is not checked

+

* Wait until the detection is done. It will say that the device is not found. Don't despair

+

* Choose Custom and then click Settings

+

* Make sure that Protocol Raw is selected and Port 9100 is entered. That will be proposed.

+

* Leave all other settings also as they were and press OK

+

* Click Next.

+

* Choose the printer driver for your printer.

+

* Click Next

+

* Give your printer a name

+

* You don't have to share the printer

+

* Next

+

* You can set it as default printer

+

* Finish

-

* At step 5: "Wait 5 minutes until WAN light turns on". I waited for 5 minutes but the WAN light never turned on (I had no ethernet cable connected to the wan port). I didn't bother to wait for the WAN light to come up but '''I did wait the 5 minutes''' to continue with step 6 and further.

* The steps above also apply for people running a converted E3000 with a stock linksys firmware. With these steps it is possible to flash your converted E3000 (running stock linksys firmware) with DD-WRT.

+

Don't forget that your routers default address is 192.168.1.1 and its port is 9100

+

=Reverting back to stock firmware=

+

To revert back to stock firmware download the latest E3000 firmware from linksys site, reset you router to defaults from within dd-wrt's webgui, wait, then login and select the stock firmware file and flash, make sure to select "reset to defaults" on the drop down menu when flashing.

+
